So I was just watching Random TV (meaning US-based drama shows, to which I'm still addicted, 5 years on), and on came an ad (which I had already seen) about identifying the symptoms of a stroke victim to get immediate action so that you minimize the damage that the stroke might do (and as we all know, time means everything when dealing with a stroke).
Could anybody do that in the states? Not bloody likely. The best you'd get is some ad for a drug that has nothing but happy old people wandering through a field of flowers saying "call your doctor for more information on Strokivius." There's no single agent that has enough pull, or enough interest in the general welfare of everybody watching TV, to advertise things like that. I mean, Readers Digest might do it in their generic "Old People Who Still Read This Health Section," but nobody who's going to attempt to target all residents.
I'm not going to claim that the UK is a Single Payer Paradise (I've used more than my share of private health insurance and care providers while I've lived here). But I love the fact that the NHS exists, and I have no problems with paying taxes to support it. Without a single major agency with the best interests of the health of all citizens around, you can't support that type of public education.
